Why Simwood Wholesale?

Stability and Availability

Our network is architected for stability and availability. Since we wholly own and operate our network, you will have shorter, more stable paths to your customers and your suppliers. We have a pathological hatred of network congestion and proactively upgrade infrastructure to maintain dramatic over-capacity and high availability. With three UK availability zones, two in the US, and traffic rerouting through any zone, the chances of our network going down is extraordinarily unlikely.

We put our money where our mouth is and provide the first 100% SLA on wholesale voice services. If we have an actual outage that means you cannot make calls out or receive calls in, we’ll pay you 25x the channel rental you paid during the period affected.

Wholesale IP Transit

At Simwood we are great advocates for direct connectivity to us in at least one site, due to the huge benefits of improved stability and performance for your voice traffic (amongst other reasons), regardless of what occurs on the wider internet. We’d love therefore to offer more customers the benefit of our IP transit to reach your customers and the wider internet. We offer IP transit in a number of different options including full and partial transit.

Wholesale SMS

Our cost-effective wholesale SMS messages can be sent through our user-friendly portal or integrated directly with your platform using our powerful API. Simwood’s high-capacity network and industry-leading fraud protection controls make Simwood a no-brainer for your wholesale messaging. SMS are, broadly speaking, either P2P (person-to-person) or A2P (application-to-person) messages. A2P is usually commercial messaging such as chat bots, OTPs, marketing and appointment reminders whereas P2P is everyday messaging, human-to-human, and should not be consumed by businesses. It is worth being aware that there are implications if businesses break the terms and conditions of a P2P plan by using them for commercial activities rather than purchasing A2Ps.

Wholesale Connectivity

When it comes to connectivity, you have a huge range of highly tailorable options via direct connectivity, multi-site solutions and IP transit. In speeds from 10Mbps to 10Gbps nationwide, we can offer ultra-low-latency un-contended connectivity from your end-users back to our core. At Simwood, we offer connectivity at several different levels, layer 2 and layer 3, depending on your specific requirements. Our transit customers can benefit from our advanced VoIP fraud enhancement, a unique offering in the industry. We co-own a dark fibre ring around London which passes through all the major data centres, meaning that customers can have their own wave on this ring with breakouts into any of the data centres in its path.
